I'm afraid my car is suffering from some rust problems around the front and rear windows and I'm pretty sure a lot of it has to do with stuff that gets trapped in between the trim and the body. Has anybody completely eliminated this trim or does it hide a lot of flaws between the window and the body? I haven't pulled this off my car yet so I really don't know whats hiding under there. Anybody got pics

 

It will look awful, without the trim. There is usually a 1/4'' of glue ooze and a step in the glass where the windshield meets the body. You'll see once you remove it.
I caulked around mine to keep the water out, but I wouldn't recommend that if you want a "nice" car.
Best to get that rust blasted and painted before major issues develop.
